- FIG. 1 illustrates a structure of an image forming apparatus 100 according to an embodiment of the present inventive concept.
- the image forming apparatus 100 may include a communication interface unit 110, a control unit 120, a user interface unit 130, a storage unit 140, and an image forming operation performing unit 150.
- the control unit 120 may include a user log-in information managing unit 121 and a log-in maintenance managing unit 122.
- the cloud-based application indicates an application providing a cloud service.
- Examples of the cloud-based application include a Google Docs application, a Google Calendar application, an Office 365 application, or the like.
- a user may store a file, such as a document, in a cloud server via a device, such as a computer or a smartphone, in which the Google Docs application is installed, and may download the file at the device from the cloud server when the user needs it.
- the cloud service may be used in an image forming apparatus, such as a multi-function printer (MFP).
- MFP multi-function printer
- the user may install and execute the Google Docs application in the MFP and then may upload a document, which is scanned by the MFP, to the cloud server or may download a document that is stored in the cloud server and output the downloaded document via the MFP in any of the forms in which an MFP outputs a document, including printing the document, faxing the document, etc.
- the communication interface unit 110 performs communication with a cloud server that provides a cloud-based application service. That is, the communication interface unit 110 exchanges data with the cloud server via a wired or a wireless communication, so that the communication interface unit 110 transmits data, which is uploaded by a user, to the cloud server, or receives user-target data from the cloud server and then provides it to the user.
- the user interface unit 130 may display a screen to the user and may receive an application execution command or the like from the user.
- the user interface unit 130 may display a list of applications installed in the image forming apparatus 100 on a display panel, such as a touch screen that is enabled to receive a touch input, and then the user may select an application to be executed by touching the application on the touch screen.
- a user identification (ID) and a password may be input via the user interface unit 130, and since it is difficult for the image forming apparatus 100 to have a separate input device, such as a computer keyboard, due to spatial limitations, the input may be performed via the touch screen.
- the input of text, such as the user ID and the password, via a user interface unit may be rather inconvenient.
- the image forming operation performing unit 150 may perform an image forming operation according to a control by the control unit 120, and in particular, the image forming operation performing unit 150 may perform an application-based operation by downloading the document file stored in the cloud server and then printing the document file or outputting the document file in another form in which an MFP outputs a document file.
- the control unit 120 controls an operation that is performed by using the cloud-based application, and manages a log-in to a user account for an application. Operations of the control unit 120 are described in detail with reference to examples below.
- the storage unit 140 may store a plurality of databases that correspond to applications, respectively, which are installed in the image forming apparatus 100.
- the image forming apparatus 100 may arrange respective databases for respective applications, and store a plurality of pieces of user log-in information that match the applications, respectively, in the databases that correspond to the applications, respectively.
- the control unit 120 manages the log-in to the user account for the application by using one of the plurality of pieces of stored user log-in information. That is, the databases that correspond to the applications, respectively, store the plurality of pieces of user log-in information that match user accounts for the image forming apparatus 100, respectively.
- the user log-in information may be required to manage the log-in to the user account for the application and may include a token that is received from the cloud server when the log-in to the user account for the application is successful.
- the user log-in information may include only the token, or may include the token and also a user ID and a password for the user account for the application.
- the token that is stored in the user log-in information may be stored after being encrypted for security.
- a database that corresponds to the Google Docs application and a database that corresponds to the Google Calendar application are separately arranged and stored in the storage unit 140.
- the image forming apparatus 100 receives a token via the communication interface unit 110 from a cloud server that provides a Google Docs service. Afterward, a space that corresponds to "user1" is generated in the database that corresponds to the Google Docs application, and then the token from the cloud server is stored in the generated space.
- the token that is stored to match "user1" corresponds to the user log-in information.
- the image forming apparatus 100 receives a token via the communication interface unit 110 from a cloud server that provides a Google Calendar service. Afterward, a space that corresponds to "user2" is generated in the database that corresponds to the Google Calendar application, and then the token from the cloud server is stored in the generated space.
- the token that is stored to match "user2" corresponds to the user log-in information.
- a user ID and a password for a user account for an application of the user may be encrypted and stored in the user log-in information. That is, the first user's user ID and password for the user account for the Google Docs application may be encrypted with the token and may be stored in the space of "user1" in the database that corresponds to the Google Docs application. Also, the second user's user ID and password for the user account for the Google Calendar application may be encrypted with the token and may be stored in the space of "user2" in the database that corresponds to the Google Calendar application.
- the storage of the user log-in information is performed by the user log-in information managing unit 121 in the control unit 120, and the log-in maintenance managing unit 122 manages a log-in to a user account for an application by using user log-in information that is stored in a database that corresponds to the application.
- the log-in maintenance managing unit 122 periodically transmits a token, which is included in the user log-in information, to a cloud server so that the log-in maintenance managing unit 122 maintains the log-in to the user account for the application.
- the log-in maintenance managing unit 122 periodically transmits the token, which is stored to match "user1" in the database that corresponds to the Google Docs application, to the cloud server that provides the Google Docs service, so that the log-in maintenance managing unit 122 allows the first user to maintain the log-in status to the user account for the Google Docs application.
- the log-in maintenance managing unit 122 periodically transmits the token, which is stored to match "user2" in the database that corresponds to the Google Calendar application, to the cloud server that provides the Google Calendar service, so that the log-in maintenance managing unit 122 allows the second user to maintain the log-in status to the user account for the Google Calendar application.
- the log-in maintenance managing unit 122 maintains the log-in status to the user account for the application by periodically transmitting the token to the cloud server, unless the user intentionally logs out from the user account for the application. Also, although the user may log out from the user account for the image forming apparatus 100, the log-in maintenance managing unit 122 periodically transmits the token to the cloud server, thereby allowing the user to maintain the log-in status to the user account for the application.
- the user may maintain the log-in status to the user account for the application. Also, unless the user intentionally logs out from the user account for the application, the user may maintain the log-in status to the user account for the application, regardless of an elapsed time from a point of time when the user last used the application.
- the user may directly use the application without performing a log-in again to that application, so that user convenience is improved.
- control unit 120 may automatically perform the log-in to the user account for the application. To do so, it is required for the user log-in information to include the user ID and the password for the user account for the application.
- the user log-in information managing unit 121 stores a user ID and a password for the user account for the Google Docs application, and also stores a token from the cloud server in the user log-in information that matches the user account for the image forming apparatus 100 in the database that corresponds to the Google Docs application. Afterward, if the user intentionally logs out from the user account for the Google Docs application, the token that is stored in the user log-in information is deleted. That is, only the user ID and the password for the user account for the Google Docs application remain in the user log-in information.
- control unit 120 may transmit the user ID and the password that are stored in the user log-in information to the cloud server, and thus may automatically perform the log-in to the Google Docs application.
- the log-in to the user account for the application is automatically performed by using the user log-in information, so that the user may skip a vexatious log-in process.

Description
- This application claims the benefit of Korean Patent Application No.
10-2013-0025248, filed on March 8, 2013 - The present inventive concept relates to a method of managing, by an image forming apparatus, a log-in to a cloud-based application, and an image forming apparatus to perform the method.
- A cloud service indicates a service by which a user may store content, such as documents, music files, images, or the like, in a cloud server and then may download content to a device, such as a smartphone, or may upload at least one piece of content to the cloud server.
- Recently, the cloud service has become widely used and thus may be used in various types of devices, and in particular, a multi-functional device enabled for network communication may use the cloud server through a cloud-based application installed therein.

- In order to use the cloud-based application in the multi-functional device, the user has to log in to the multi-functional device via a multi-functional device account and then log in again via an account of an application. However, it is inconvenient for the user to be required to input text to repeat a log-in process whenever the user uses an application in the multi-functional device. Also, after the user logs into the multi-functional device, the user may want to easily use applications without separate log-in processes, and thus, there is an increasing demand for a technology capable of satisfying user needs.

- These and/or other features and utilities of the present general inventive concept will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
-
FIG. 1 illustrates a structure of an image forming apparatus according to an embodiment of the present inventive concept; -
FIGS. 2 through 5 illustrate operations that are performed in the image forming apparatus and a cloud server when a method of managing a log-in to a cloud-based application is performed, according to embodiments of the present inventive concept; and -
FIGS. 6 through 9 are flowcharts of a method of managing a log-in to a cloud-based application, according to embodiments of the present inventive concept. - Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept while referring to the figures.
-
FIG. 1 illustrates a structure of animage forming apparatus 100 according to an embodiment of the present inventive concept. Referring toFIG. 1 , theimage forming apparatus 100 may include acommunication interface unit 110, acontrol unit 120, auser interface unit 130, astorage unit 140, and an image formingoperation performing unit 150. Also, thecontrol unit 120 may include a user log-ininformation managing unit 121 and a log-inmaintenance managing unit 122. - Before each element of the
image forming apparatus 100 is described, first, a cloud-based application is briefly described. - The cloud-based application indicates an application providing a cloud service. Examples of the cloud-based application include a Google Docs application, a Google Calendar application, an Office 365 application, or the like. For example, a user may store a file, such as a document, in a cloud server via a device, such as a computer or a smartphone, in which the Google Docs application is installed, and may download the file at the device from the cloud server when the user needs it.
- Also, the cloud service may be used in an image forming apparatus, such as a multi-function printer (MFP). For example, the user may install and execute the Google Docs application in the MFP and then may upload a document, which is scanned by the MFP, to the cloud server or may download a document that is stored in the cloud server and output the downloaded document via the MFP in any of the forms in which an MFP outputs a document, including printing the document, faxing the document, etc.
- Referring back to
FIG. 1 , elements of theimage forming apparatus 100 will now be described in detail. - The
communication interface unit 110 performs communication with a cloud server that provides a cloud-based application service. That is, thecommunication interface unit 110 exchanges data with the cloud server via a wired or a wireless communication, so that thecommunication interface unit 110 transmits data, which is uploaded by a user, to the cloud server, or receives user-target data from the cloud server and then provides it to the user. - The
user interface unit 130 may display a screen to the user and may receive an application execution command or the like from the user. For example, theuser interface unit 130 may display a list of applications installed in theimage forming apparatus 100 on a display panel, such as a touch screen that is enabled to receive a touch input, and then the user may select an application to be executed by touching the application on the touch screen. Also, in a case of a user log-in, a user identification (ID) and a password may be input via theuser interface unit 130, and since it is difficult for theimage forming apparatus 100 to have a separate input device, such as a computer keyboard, due to spatial limitations, the input may be performed via the touch screen. In general, the input of text, such as the user ID and the password, via a user interface unit may be rather inconvenient. - The image forming
operation performing unit 150 may perform an image forming operation according to a control by thecontrol unit 120, and in particular, the image formingoperation performing unit 150 may perform an application-based operation by downloading the document file stored in the cloud server and then printing the document file or outputting the document file in another form in which an MFP outputs a document file. - The
control unit 120 controls an operation that is performed by using the cloud-based application, and manages a log-in to a user account for an application. Operations of thecontrol unit 120 are described in detail with reference to examples below. - The
storage unit 140 may store a plurality of databases that correspond to applications, respectively, which are installed in theimage forming apparatus 100. Theimage forming apparatus 100 may arrange respective databases for respective applications, and store a plurality of pieces of user log-in information that match the applications, respectively, in the databases that correspond to the applications, respectively. Also, thecontrol unit 120 manages the log-in to the user account for the application by using one of the plurality of pieces of stored user log-in information. That is, the databases that correspond to the applications, respectively, store the plurality of pieces of user log-in information that match user accounts for theimage forming apparatus 100, respectively. - Here, the user log-in information may be required to manage the log-in to the user account for the application and may include a token that is received from the cloud server when the log-in to the user account for the application is successful. Here, the user log-in information may include only the token, or may include the token and also a user ID and a password for the user account for the application. The token that is stored in the user log-in information may be stored after being encrypted for security.
- For example, in a case where the Google Docs and Google Calendar applications are installed in the
image forming apparatus 100, a database that corresponds to the Google Docs application and a database that corresponds to the Google Calendar application are separately arranged and stored in thestorage unit 140. - If a first user, whose user ID for a user account for the
image forming apparatus 100 is "user1," logs into theimage forming apparatus 100, executes the Google Docs application, and then logs into a user account for the Google Docs application, theimage forming apparatus 100 receives a token via thecommunication interface unit 110 from a cloud server that provides a Google Docs service. Afterward, a space that corresponds to "user1" is generated in the database that corresponds to the Google Docs application, and then the token from the cloud server is stored in the generated space. Here, the token that is stored to match "user1" corresponds to the user log-in information. - Also, if a second user, whose user ID for a user account for the
image forming apparatus 100 is "user2," logs into theimage forming apparatus 100, executes the Google Calendar application, and then logs into a user account for the Google Calendar application, theimage forming apparatus 100 receives a token via thecommunication interface unit 110 from a cloud server that provides a Google Calendar service. Afterward, a space that corresponds to "user2" is generated in the database that corresponds to the Google Calendar application, and then the token from the cloud server is stored in the generated space. Here, the token that is stored to match "user2" corresponds to the user log-in information. - As described above, a user ID and a password for a user account for an application of the user may be encrypted and stored in the user log-in information. That is, the first user's user ID and password for the user account for the Google Docs application may be encrypted with the token and may be stored in the space of "user1" in the database that corresponds to the Google Docs application. Also, the second user's user ID and password for the user account for the Google Calendar application may be encrypted with the token and may be stored in the space of "user2" in the database that corresponds to the Google Calendar application.
- The storage of the user log-in information is performed by the user log-in
information managing unit 121 in thecontrol unit 120, and the log-inmaintenance managing unit 122 manages a log-in to a user account for an application by using user log-in information that is stored in a database that corresponds to the application. - In more detail, the log-in
maintenance managing unit 122 periodically transmits a token, which is included in the user log-in information, to a cloud server so that the log-inmaintenance managing unit 122 maintains the log-in to the user account for the application. In the aforementioned two examples, the log-inmaintenance managing unit 122 periodically transmits the token, which is stored to match "user1" in the database that corresponds to the Google Docs application, to the cloud server that provides the Google Docs service, so that the log-inmaintenance managing unit 122 allows the first user to maintain the log-in status to the user account for the Google Docs application. - Also, the log-in
maintenance managing unit 122 periodically transmits the token, which is stored to match "user2" in the database that corresponds to the Google Calendar application, to the cloud server that provides the Google Calendar service, so that the log-inmaintenance managing unit 122 allows the second user to maintain the log-in status to the user account for the Google Calendar application. - The log-in
maintenance managing unit 122 maintains the log-in status to the user account for the application by periodically transmitting the token to the cloud server, unless the user intentionally logs out from the user account for the application. Also, although the user may log out from the user account for theimage forming apparatus 100, the log-inmaintenance managing unit 122 periodically transmits the token to the cloud server, thereby allowing the user to maintain the log-in status to the user account for the application. - Thus, once the user logs into the user account for the application, although the user logs out from the user account for the
image forming apparatus 100 and then logs in again to the user account for theimage forming apparatus 100, the user may maintain the log-in status to the user account for the application. Also, unless the user intentionally logs out from the user account for the application, the user may maintain the log-in status to the user account for the application, regardless of an elapsed time from a point of time when the user last used the application. - In conclusion, once the user logs into the user account for the application, the user may directly use the application without performing a log-in again to that application, so that user convenience is improved.
- When the user inputs an application execution command while the user does not log into the user account for the application, the
control unit 120 may automatically perform the log-in to the user account for the application. To do so, it is required for the user log-in information to include the user ID and the password for the user account for the application. - In more detail, for example, when the user that logs into the user account for the
image forming apparatus 100 logs into a user account for the Google Docs application, the user log-ininformation managing unit 121 stores a user ID and a password for the user account for the Google Docs application, and also stores a token from the cloud server in the user log-in information that matches the user account for theimage forming apparatus 100 in the database that corresponds to the Google Docs application. Afterward, if the user intentionally logs out from the user account for the Google Docs application, the token that is stored in the user log-in information is deleted. That is, only the user ID and the password for the user account for the Google Docs application remain in the user log-in information. Thus, after the user logs out from the user account for the Google Docs application, if the user executes the Google Docs application, thecontrol unit 120 may transmit the user ID and the password that are stored in the user log-in information to the cloud server, and thus may automatically perform the log-in to the Google Docs application. - As described above, when the user who logged in and then logged out from the user account for the application executes the application, the log-in to the user account for the application is automatically performed by using the user log-in information, so that the user may skip a vexatious log-in process.

FIGS. 2 through 5 illustrate operations that are performed in theimage forming apparatus 100 and acloud server 200 when a method of managing a log-in to a cloud-based application is performed, according to embodiments of the present inventive concept. Hereinafter, the method of managing a log-in to a cloud-based application is described in detail with reference toFIGS. 2 through 5 . - Referring to
FIG. 2 , in operation S201, a user logs into a user account for theimage forming apparatus 100, and then, in operation S202, the user logs into a user account for an application. When the log-in to the user account for the application is successful, in operation S203, thecloud server 200 transmits a token to theimage forming apparatus 100. When theimage forming apparatus 100 receives the token from thecloud server 200, in operation S204, theimage forming apparatus 100 stores the token in user log-in information that is stored in a database corresponding to the application. Here, the token is stored in the user log-in information that matches the user account for theimage forming apparatus 100. - After the token is stored in the user log-in information, in operation S205, the
image forming apparatus 100 periodically transmits the token in the user log-in information to thecloud server 200, thereby allowing the user to maintain the log-in to the user account for the application. Although the user logs out from the user account for theimage forming apparatus 100, theimage forming apparatus 100 periodically transmits the token in the user log-in information to thecloud server 200, thereby allowing the user to maintain the log-in status to the user account for the application. Also, regardless of an elapsed time from a point of time when the user last used the application, theimage forming apparatus 100 periodically transmits the token to thecloud server 200, thereby allowing the user to maintain the log-in status to the user account for the application. - However, if the user intentionally logs out from the user account for the application, the token is deleted from the user log-in information and the transmission of the token no longer occurs.
- Referring to
FIG. 3 , in operation S301, a user logs into a user account for theimage forming apparatus 100, and then, in operation S302, the user inputs an application execution command. In operation S303, theimage forming apparatus 100 checks user log-in information in a database that corresponds to an application. That is, theimage forming apparatus 100 checks the user log-in information, which corresponds to the user account for theimage forming apparatus 100, from the database that corresponds to the application for which the application execution command is input. - If a token is included in the checked user log-in information, it means that a user's log-in to a user account for the application is maintained, and thus, in operation S304, an application execution screen is displayed to the user. Then, in operation S305, the
cloud server 200 provides an application service according to a user input, and although a use of the application has ended, in operation S306, theimage forming apparatus 100 periodically transmits the token included in the user log-in information to thecloud server 200, thereby maintaining the log-in status to the user account for the application. - Referring to
FIG. 4 , in operation S401, a user logs into a user account for theimage forming apparatus 100, and then, in operation S402, the user inputs an application execution command. In operation S403, theimage forming apparatus 100 checks user log-in information in a database that corresponds to an application. That is, theimage forming apparatus 100 checks the user log-in information, which corresponds to the user account for theimage forming apparatus 100, from the database that corresponds to the application for which the application execution command is input. - If a token is not included in the checked user log-in information, it means that a user's log-in to a user account for the application has not been maintained, and thus, in operation S404, a screen for a log-in to the user account for the application is displayed to the user. In operation S405, the
image forming apparatus 100 waits to receive a user ID and a password from the user, and in operation S406 after the user ID and password have been received, theimage forming apparatus 100 attempts an automatic log-in by transmitting the received user ID and the password to thecloud server 200. When the log-in is successful (user ID and password are correct), in operation S407, thecloud server 200 transmits the token to theimage forming apparatus 100, and in operation S408, theimage forming apparatus 100 stores the received token in the user log-in information. In operation S409, theimage forming apparatus 100 periodically transmits the token that is stored in the user log-in information to thecloud server 200, thereby maintaining the log-in status to the user account for the application. - Although the user logs out from the user account for the
image forming apparatus 100, theimage forming apparatus 100 periodically transmits the token in the user log-in information to thecloud server 200, thereby maintaining the log-in status to the user account for the application. Also, regardless of an elapsed time from a point of time when the user last used the application, theimage forming apparatus 100 periodically transmits the token to thecloud server 200, thereby maintaining the log-in status to the user account for the application. - Referring to
FIG. 5 , in operation S501, a user logs into a user account for theimage forming apparatus 100, and then, in operation S502, the user inputs an application execution command. In operation S503, theimage forming apparatus 100 checks user log-in information in a database that corresponds to an application. That is, theimage forming apparatus 100 checks the user log-in information, which corresponds to the user account for theimage forming apparatus 100, from the database that corresponds to the application for which the application execution command is input. - If a token is not included in the checked user log-in information, it means that a user's log-in to a user account for the application has not been maintained, and thus, in operation S504, the
image forming apparatus 100 attempts an automatic log-in to the user account for the application by using the user log-in information. Thus, in operation S505, theimage forming apparatus 100 transmits a user ID and a password that are included in the user log-in information to thecloud server 200, and when the log-in is successful, in operation S506, thecloud server 200 transmits the token to theimage forming apparatus 100. - In operation S507, the
image forming apparatus 100 stores the received token in the user log-in information, and in operation S508, theimage forming apparatus 100 periodically transmits the token that is included in the user log-in information to thecloud server 200, thereby maintaining the log-in to the user account for the application. -
FIGS. 6 through 9 are flowcharts of a method of managing a log-in to a cloud-based application, according to exemplary embodiments of the present inventive concept. Hereinafter, the method of managing a log-in to a cloud-based application according to exemplary embodiments is described in detail with reference toFIGS. 6 through 9 . - Referring to
FIG. 6 , in operation S601, a user logs into a user account for a multi-function printer (MFP), and then, in operation S602, the user logs into a user account for an application. When the log-in to the user account for the application is successful, in operation S603, the MFP receives a token from a cloud server. In operation S604, the MFP stores the token in user log-in information in a database that corresponds to the application, and in operation S605, the MFP periodically transmits the token that is stored in the user log-in information to the cloud server, thereby maintaining the log-in status to the user account for the application. - Although the user logs out from the user account for the MFP, the MFP periodically transmits the token in the user log-in information to the cloud server, thereby maintaining the log-in status to the user account for the application. Also, regardless of an elapsed time from a point of time when the user last used the application, the MFP periodically transmits the token to the cloud server, thereby maintaining the log-in status to the user account for the application.
- As described above, unless the user intentionally logs out from the user account for the application, the log-in status to the user account for the application is maintained, so that once the user logs into the user account for the application, the user may directly use the application without being required to perform a log-in process again.
- Referring to
FIG. 7 , in operation S701, a user logs into a user account for a MFP. After the user logs into the user account for the MFP, in operation S702, the user inputs an execution command to execute an application that is installed in the MFP, via a user interface unit of the MFP. After the MFP receives the execution command to execute the application, in operation S703, the MFP checks user log-in information in a database that corresponds to the application. In operation S704, as a result of checking whether the user log-in information includes a token, if the token is included, the method proceeds to operation S710, in which the MFP displays an application execution screen on a display unit. - However, in operation S704, as a result of the checking, if the user log-in information does not include the token, the method proceeds to operation S705, in which the MFP displays a screen for a log-in to a user account for the application on the display unit. In operation S706, the user logs into the user account for the application by inputting a correct user ID and a password. When the log-in is successful (correct ID and password), in operation S707, the MFP receives a token from a cloud server, and then in operation S708, the MFP stores the received token in the user log-in information in the database that corresponds to the application. In operation S709, the MFP periodically transmits the token that is included in the user log-in information to the cloud server, thereby maintaining the log-in to the user account for the application.
- Referring to
FIG. 8 , in operation S801, a user logs into a user account for a MFP, and then, in operation S802, the user logs into a user account for an application. When the log-in to the user account for the application is successful, in operation S803, the MFP receives a token from a cloud server. In operation S804, the MFP stores a user ID and a password of the user of the user account for the application, and the received token in user log-in information in a database that corresponds to the application, and in operation S805, the MFP periodically transmits the token that is stored in the user log-in information to the cloud server, thereby maintaining the log-in to the user account for the application. - Although the user logs out from the user account for the MFP, the MFP periodically transmits the token in the user log-in information to the cloud server, thereby maintaining the log-in status to the user account for the application. Also, regardless of an elapsed time from a point of time when the user last used the application, the MFP periodically transmits the token to the cloud server, thereby maintaining the log-in status to the user account for the application.
- As described above, unless the user intentionally logs out from the user account for the application, the log-in status to the user account for the application is maintained, so that once the user logs in to the user account for the application, the user may directly use the application without being required to perform a log-in process again.
- Referring to
FIG. 9 , in operation S901, a user logs into a user account for a MFP. After the user logs into the user account for the MFP, in operation S902, the user inputs an execution command to execute an application that is installed in the MFP, via a user interface unit of the MFP. After the MFP receives the execution command to execute the application, in operation S903, the MFP checks user log-in information in a database that corresponds to the application. In operation S904, as a result of checking whether the user log-in information includes a token, if the token is included, the method proceeds to operation S910, in which the MFP displays an application execution screen on a display unit. - However, in operation S904, as a result of the checking, if the user log-in information does not include the token, the method proceeds to operation S905, in which the MFP automatically attempts a log-in to a user account for the application by using the user log-in information. That is, the MFP transmits the user ID and the password that are included in the user log-in information to the cloud server. If the log-in is successful, in operation S906, the MFP receives a token from the cloud server. Then, in operation S907, the MFP stores the received token in the user log-in information, and in operation S908, the MFP periodically transmits the token that is included in the user log-in information to the cloud server, thereby maintaining the log-in to the user account for the application.
- As described above, when the user who logged in and then logged out from the user account for the application executes the application, the log-in to the user account for the application is automatically performed by using the user log-in information, so that the user may skip a vexatious log-in process.
- According to exemplary embodiments of the present inventive concept, the image forming apparatus stores the user log-in information in the database that corresponds to the application installed in the image forming apparatus, so as to match the user log-in information with a user account for the image forming apparatus, and then the image forming apparatus maintains the log-in to the user account for the application by using the stored user log-in information, so that the user may directly use the application in the image forming apparatus without a vexatious log-in process.
- Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles of the general inventive concept, the scope of which is defined in the appended claims.
- Attention is directed to all papers and documents which are filed concurrently with or previous to this specification in connection with this application and which are open to public inspection with this specification.
- All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
- Each feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
